Attenuator bụ akụkụ njikwa nke isi ọrụ ya bụ iji belata ike mgbaàmà na-agafe na attenuator. Na ngwa bara uru, RF attenuators nwere ike ịrụ ọrụ na gburugburu ọnọdụ okpomọkụ dị iche iche, na-eme ka attenuators edozi lcryogenic. Anyị haziri attenuators maka ala okpomọkụ gburugburu (-269 ~ + 125 degrees Celsius) site na-ahọpụta ndị kwesịrị ekwesị akụrụngwa na imeziwanye larịị nke nkà na ụzụ.

Cryogenic attenuators ofu nwere ezi thermal conductivity na elu kwụsie ike na oke ala okpomọkụ. N'otu aka ahụ, a na-eji attenuator microwave mee ihe dị ka ihe mgbaàmà amplitude attenuators, na n'aka nke ọzọ, millimeter wave attenuator nwere ike iji dị ka okpomọkụ sinks maka oyi mbufe. Enwere ike iji Mm wave attenuator n'ọhịa dị ka nyocha oghere miri emi, mbara igwe redio, kọmpụta kọmpụta, na nkwurịta okwu ikuku, ọkachasị na nnwale physics dị ala na nyocha nke superconductor.

Ebumnuche:

1. Attenuation Signal: A na-eji ndị na-eme ka attenuators nke Cryogenic mee ka ike RF na ngwa ndakwa nri belata n'ụzọ ziri ezi na gburugburu ebe okpomọkụ dị oke ala. Nke a dị mkpa maka ichedo akụrụngwa nnabata nke nwere mmetụta yana ịchịkwa ọkwa mgbaàmà.
2. Njikwa mkpọtụ: Site n'ịgbasa mgbaàmà ahụ, ụda na nnyonye anya na usoro nwere ike ibelata, si otú ahụ na-emeziwanye akara ngosi-na-noise ratio (SNR) nke mgbaàmà.
3. Mkparịta ụka na-adaba adaba: Enwere ike iji ndị na-emepụta ihe na-emepụta ihe na-eme ka a na-eme ka ọ bụrụ ihe na-eme ka usoro ahụ dịkwuo mma, si otú a na-ebelata ntụgharị uche na ebili mmiri guzoro ma na-emeziwanye arụmọrụ usoro.

1. Nnwale physics nke Cryogenic: N'ime nyocha physics dị ala, a na-eji attenuators cryogenic na-achịkwa ma dozie ike mgbaàmà. Nnwale ndị a na-agụnyekarị ọmụmụ nke superconductors, mgbakọ quantum na ihe ndị ọzọ dị ala.
2. Nchọpụta Superconductor: Na nyocha nke superconductor, a na-eji ndị na-eme ihe na-eme ka a na-eme ihe na-eme ka a na-achịkwa ma na-achịkwa ugboro redio na ngwa ndakwa nri iji mụọ ihe onwunwe na omume nke superconductor.
3. Computing Quantum: N'ime usoro nhazi nke quantum, a na-eji attenuator nke a na-akpọ cryogenic eme ihe iji dozie ike mgbaàmà na mmekọrịta n'etiti quantum bits (qubits). Nke a dị oke mkpa maka ịrụ ọrụ mgbako quantum dị elu.
4. Astronomy na Radio Telescopes: Na mbara igwe na usoro teliskop redio, a na-eji RF attenuators dozie ike nke akara eluigwe natara. Nke a na-enyere aka melite ogo na izi ezi nke data nleba anya.
5. Ngwa Eletrọnịkị Cryogenic: Na ngwa elektrọn dị ala, a na-eji attenuator microwave na-achịkwa ma mezie ike mgbaàmà iji hụ na arụ ọrụ nkịtị na arụmọrụ dị elu nke akụrụngwa.
Na nkenke, a na-eji ndị na-eme ihe ike na-eme ihe n'ọtụtụ ebe dị ka nnwale physics cryogenic, nchọpụta superconductor, kọmpụta quantum, mbara igwe, na akụrụngwa eletrọnịkị cryogenic. Ha na-emeziwanye arụmọrụ sistemu na ntụkwasị obi site na ịchịkwa ike mgbaama na ibelata mkpọtụ.

QualwaveỌ na-enye ndị na-eme ihe dị elu dị elu nke dị elu cryogenic na-ekpuchi ogologo oge DC ~ 40GHz. Nkezi ike bụ 2 watts. A na-eji attenuators eme ihe n'ọtụtụ ngwa ebe achọrọ mbelata ike.
